I fully potty trained my 2.5yr old DD about 5 or 6 weeks ago - she hasn't had a single accident (wee or poo) since the first week and not even in the night...she ALWAYS wakes up and says "mummy I need a wee".
However, for the last 4 or 5 times she has gone to preschool (she goes twice a week) she has had an "accident" there every time. I don't believe she would just wee or poo herself without telling someone she needs the loo, because she hates the feeling so much, she has no accidents at home and she had no accidents at preschool either for the first couple of weeks after potty training. They tell me she does say when she needs the loo, but I can't get a proper answer about why or how these accidents keep happening. I also don't have much faith in them because when I first told them she was trained, she came home desperately thirsty the next couple of times and I assume they gave her little/nothing to drink to avoid accidents.
I know they have lots of kids to watch, so she must be either telling someone she needs the loo and they can't act on it quick enough (although she does give good notice and is very good at holding), or they are forgetting her, or I guess there's a chance she is a completely different person at preschool and gets too distracted to say she needs the loo.
DH is really angry and thinks they're neglecting her. I've asked them a few times now what happens with these accidents but only get a vague non-answer (almost like a shrug), so if I ask again it will have to be put a bit stronger. Would I be unreasonable to have a serious chat with them about this?
